FLASH-LIGHT.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed May 12, 1919. Serial No. 296,300.

To all whom t may concern.'

Be it known that I, GUsTAvE FRANKEL, a citizen of the United States,residing at 666 lVest 162d street, New York city, in the county ofNewYork and State of New York, have'invented certain new and useful11nprovements in Flash-Lights, of which the following is aspecification.

This invention relates to a flashlight construction.

Portable electric lamps, which derive their supply of current from oneor more batteries are very well known. They usually embody a smallelectric bulb, means for connecting it to the batteries including aswitch, and a small lens which projects the light in the desired manner.

One of the objects of my new and improved construction is to assemblethe flashlight battery together with the lens and electric globe so asto provide a simple and eiicient switch for providing a continuous or anintermittent light.

Other objects of my invention will be described in the followingspecification and drawings which illustrate a preferred embodimentthereof.

f Figure 1 is a vertical section partially in elevation. l j j y Fig. 2is a vertical elevation partially in section and showing a differentembodiment, and Fig. 3 is a plan view.

The lens 1 is suitably connected to a metal casing 2. The bulb, which isnot shown in the drawings because it is in itself an old and well knownpart, and as such forms no part of my invention, is held in the head 3of the casing 2, so that its light is properly refracted by the lens 1.The head 3 is connected to the casing 2 by any suitable means and it maybe detachable, for affording access to thelens and to the globe.

The current is supplied from a battery 1, which has an envelop separatedfrom the casing 2, so that it may be taken out and replaced by a newbattery.

One terminal of the electric bulb is connected to the metal casing 2, soas to be in circuit therewith, and the other terminal is connected to aninsulated binding post located at the rear end of the head 3. Thisinsulated binding post or terminal is adapted to contact with a-bindingpost or pole located at the adjacent end of the battery 4, when thebattery 4 is inserted into the proper position, which is shown in thedrawings.

The other pole or terminal of the battery 4, is located at the oppositeend of the battery 4r and is adapted to contact with the coil spring 57which also firmly maintains the battery 4t in proper position so as toprovide contact between the said insulated terminal of the lamp and theadjacent pole of the battery.

The rear end of the casing 2 is closed by a cap 6,'which is suitablythreaded as shown so as to be detachably secured to the casing 2. Thiscap 6 has a base 7, made of some insulating composition, in which ametal member 8 is embedded so as to be irmly secured thereto, and alsosupport the spring 5 which may be detachable therefrom or which may besecured thereto.

The metal casing 2 has a sheath 9 of insulating composition securedthereto, and a metal member 10, which is located in this sheath, andinsulated thereby from the casing 2, is adapted to have its lower endcontact with the base member S, when the base 6 is secured in properposition.

The casing 2 has a metal extension 11 secured thereto by rivets or anyother suitable means, and ,this has a seat 12 made of suitableinsulating material secured thereto, and also if desired to the casing2. A binding post or terminal 14. which is secured and thereforeconnected to the circuit member 10, projects beyond the seat 12.

The extension 11 has a sliding button 15 slidably secured thereto. Thisbutton 15 carries a switch arm 16 which is curved so that it is adaptedto Contact with the curved terminal 14.

The seat 11 is also provided with a metal arm 18, which is provided witha head 19 that projects through the seat 11.

The operation of the apparatus is as follows By simply putting thebattery et into place, and screwing on the cap 6, one pole of thebattery is put into contact with the insulated terminal of the bulb orglobe, and the other pole is put into contact with the metal base member8. Since the metal button 15 is in contact with the metal extension 11of the casing 2, by suitably sliding the button 15 toward the lens,until the switch arm 16 is in contact with the terminal 14:, the circuitis completed and a continuous light is secured.

The preferred method of making and assembling the structure shown in thedrawings is as follows z- 2 i 1,332,8es

ceivers of telephones and for similar pur-v poses. Such a compositioncan be molded under great pressure, such as can be supplied by means ofa hydraulic press, andv the cap 6, its base 7, and its base member 8,are all assembled by molding under pressure, so that insulating base 7firmly holds both the cap 6 and the lbase member 8. This constructionobviates the need of all rivets or similar parts and hence is moreeconomical and etlicient.

As shown in the drawings, the base member S has inturned portions, orlanges which are irmly embedded in the moldable insulating composition.

The insulating base or seat 12 of the eX- tension 11 is made oi' asimilar composition and isy secured inplace by the terminal 14a which isconnected to the stationary circuit member 10 and also by the resilientarm 18 which is united therewith by molding under suiiicient pressure,and which has the same contour as the extension 11 as shown in Fig. 1. t

If desired the case 2 of the iiashlight could be made of some insulatingmaterial, and one terminal of the lamp could then be connected to thepost 14 by some suitable conductor.

I have described a preferred embodiment of my invention, but it is clearthat numerousfchanges could be made in detail without departing from itsspirit.

I claim 1; In a flashlight, the combination of a metal case having oneof its ends open, an electric lamp carried thereby and having one of itsterminals in circuit with said metal case and the other terminalinsulated therefrom, a battery having terminals at f other terminalagainst that terminal of the lamp which is insulated from the casing, a

stationary circuit member insulated from the said casing, and separatefrom and adapted to contact with the said base member when the said capis placed in its proper position, and switch means adapted to place saidstationary circuit member into and out of circuit with the casing.

2. In aV flashlight,a metal case carrying .Y an electric lamp, one ofthe terminals of the said lam-p beingzconnected to the said case and theother terminal being insulated therefrom, a battery having terminals atits ends, one of the ends of the said casing being open and having a capprovided with an insulated base for closing the said open end, aconducting base member connected to the said insulated base and carryinga spring, said spring being adapted to contact with one of the terminalsof the said battery and force the other terminal against that terminalof the lamp which is insulated from the said case, a stationary circuitmember secured to and insulated frolnthe said casing and adapted tocontact with the said conducting base member when the said cap is inproper position, the said casing having a metal extension secured to thesaid case and provided with a seat made of moldable insulatingcomposition, a terminal passing through the said seat and connected tothe said circuit member, and adapted to retain the said seat in itsplace, and switch means located in the said extension and adapted toplace the said last mentioned terminal into and out of contact with thesaid eXtension and the said casing.

3. In a flashlight, a metal case carrying an electric lamp, one of theterminals of the said lamp being connected to the said case and theother terminal being insulated therefrom, a battery having terminals atits ends, one of the ends of the said casing being open and having a capprovided with an insulated base for closing the saidopen end,
